Analyte Sensor

Abstract: in one embodiment, a working electrode to detect the presence of an analyte is disclosed. the working electrode includes an electrical insulator having a well. the working further includes an electrical conductor that is positioned at the bottom of the well and a reactive chemistry that includes a dehydrogenase based enzyme and cofactor at least partially filling the well. where the reactive chemistry has a minimum molecular weight and a hydrogel is located over the reactive chemistry. the hydrogel is in contact with the insulation and the reactive chemistry and the hydrogel has a porosity less than the minimum molecular weight of the reactive chemistry.
